symmetric vs. asymmetric [was: Verizon Policy Statement on Net Neutrality]

Frank,

Are your measurements taken at the campus boundary or within the campus network?

I remember the confusion when Centrex was first introduced at UMich. The statistic there that confounded was call durations wildly exceeding models, but mostly within the campus, not to the outside world.  Could there be peer to peer traffic that you do not see?
